OTTO WILLIAM MEISSNEB, OF WEST-MOUNT, QUEBEC, CANADA.

DUMP-can.

Be it known that I, O'rro WILLIAM Mares- NER, of the townof Westmount, l?rovince of Quebec, Canada, have invented certain new and useful Improvements in Dump-Cars.

My invention has for its object to provide a hopper bottom car which will be more durable without increase of cost of con struction, and adapted to have a greater proportion of a. given load carried-by a central member than has been possible in hopper bottom cars heretofore known.

The invention may be said briefly to consist of the several combinations and ar-' rangements of parts hereinafter set forth and pointed out in the claims. comprehension, however of my invention reference must be had to the-accompa nying drawings forming a part-of this application and wherein, Figures 1 and 2 are side elevations, partly in longitudinal section, ofthe halves of my improved dump car; Figs. 3 and 4 are horizontal longitudinal sectional views taken on line A A Figs. 1 and 2; Fig. 5 is a transverse sectional view taken on line B BFig. 4; Fig. 6 is an enlarged vertical sectional view illustrating the lunged connection between the car body and the'false floor members which cover the trap doors; Fig. 7 is a plan view of the parts illustrated in Fig. 6; and Fig. 8 is an enlarged detail view of the means for oper ating a portion of the door mechanism.

The car body comprises a hopper bottom of particular construction supporting l\tll e V improved-hopper bottom comprising a cen-- ter sill b in the form of a box girder having laterally extending arms 0 riveted or otherwise rigidly secured thereto and spaced to accommodate and entirely support a series of hoppers between pairs thereof, each arm being in efiecta cantaliver. -Thearms over I thebearing members of the truck act as bolsters and other arms c act as cross-bearers. Each of these bolster arms and two of the intermediate arms consist of webs'o' and angle irons c riveted thereto, while the remaining cross=bearers are of vertically disposed channel form in cross-section. Of the hoppers the walls,-d, which are transverse to the car, extend downwardly from Specification 0t Letters Patent. Application filed necember 14, 1908. Serial No. 467,5

For full paged as just flanged door frame 6, and each of the other walls of suchhoppers consists of vertical andinclined portions 9 and h respectively,

the inclined portions of the walls contiguous to the center sill being flanged as at a and riveted thereto at a point slightly below the middle thereof, while the walls 0) conform to the outline presented bythe side edges of the walls 9', h. With this construction the hoppers are entirely supported,

in suspension, by the lateral arms and in I dependently of the sides of the car body, and the arms being fixed to and wholly supported by the center sill',the latter carries a trough particularly adapted for rapid unloading. These .doors are hinged, trans- "ersely' to the car, at their flanged ends upon shafts mounted in bearings 5 upon the transverse walls 0? of the'hoppers and when closed their flanges inclose one end and. the side flanges of the frame 6, which constitutes the mouth of the hopper and has its flanges extending downwardly to be enmentioned by the door flanges. The open ends of the doors are closed by angular valwilar members 6 car ried by quadrantal gears 7 supported on pinions' 9 mounted upon shafts 10 through square ends 12 by means of a wrench or other suitable means, the quadrant riding upon the pinions during operation and ,the latter being controlled by a ratchet and pawl 13 and 14 holding the valvular mem bers in closed position. I

'The doors are operated by shafts 15 retatably mounted thereon and chains 16 at tached atone end to the exterior of the at their opposite ends to the shafts 15, such chains being of suitable length to supportthe doors when full open at an angle of, up

proximately, forty-five 'de recs, while the closing of the doors elfeo'teddiy turning Patented Apr. 9, 1512,

the shafts and causing them to climb-the chains, thus lifting the doors to the door to accommodate the improved hinges 'whi ch i are further accommodated by cutting away the contiguous portions of the floor menu-f horses at 24. These improved hinges com *priselflform bearings '25 riveted as at 26- ltothe angle iron side'stifieners 27 of the car, straps 28 (preferably angle irons) ea:-v tendin'g completely acpossea'ch floor mem bcrjand, binding its component parts togetlier, and links inthe form of stirrups and composed ofai staple 30 and yoke 31, the legs of the staple being passed one through both flanges ofthe bearing and the other through-the endof the strap -28 which formed with an eye 29 for t e purpose.

The principal loading doors near the ends are indicated at '40, and auxiliary doors 4:1

are also provided to enable a loose commodity tobe fed into the ends of the car thus obviating the necessity of trimming the load. f a

.When the car is utilized as a carrier for whose commodity such as grain or the like the raised fiooninembers afford the required interior fgrain doors and reinforcements for the sides, and the attachment of the inner longitudinal walls of the hoppers to the center sill at a point midway of its height more effectively transmits the grain load to such center sill and at the same time saves J-matemal 1n the construction of these longitudinal walls; while owing to the fact that the load of practically the whole cargo is carried bythe said center sill, the side sills and other members usuall serving the purpose can be constructed 0 less weight, there by effecting considerable saving in cost. The member 6 While serving to prevent leakage at the open end of the door also serves.
